I'm not sure but in the beginning it looks like you changed the aspect ratio of your vcam when you were panning it. If you did then yeah don't do that. Makes everything look inconsistent.

Outside of that it was pretty decently well animated. When you have characters hit each other you need to throw in a bit of hitstun as well. Adding hitstun will give your attacks more weight and make them feel stronger. Additionally some camera shake might need to be added depending on how strong the hit was. But yeah you're doing good, keep it going!
